Dear all, I am compiling a C++ code a colleague sent me with some references to string.h library. He compiled the code in gcc-3.4.1 under Mandrake. I am trying to do the same using gcc-3.4.2 under Debian but I got these errors: > In file included from /usr/include/c++/3.4/cstring:49, > from /usr/include/c++/3.4/bits/char_traits.h:45, > from /usr/include/c++/3.4/string:47, > from ../base/devicebase.h:9, > from device.h:9, > from devicelan.h:9, > from devicelan.cpp:6: > /usr/include/c++/3.4/cstddef:52: error: `::ptrdiff_t' has not been declared > /usr/include/c++/3.4/cstddef:53: error: `::size_t' has not been declared - "devicelan.cpp" includes in line 6 "devicelan.h" - "devicelan.h" includes in line 9 "device.h" - "device.h" includes in line 9 "devicebase.h" - "devicebase.h" includes in line 9 "string" Maybe It is a well known problem, I tried to compile a hello world program with a string.h include and it works perfectly...Dont know where I should head my search... Best Regards Miguel
